Conquer "Catalina Crush" Hill

Come earn your buffalo finisher medal by experiencing Catalina Crush, a famous hill at mile 19 of the marathon course.  After conquering the hill stop at the mile 19 aid station to gulp down an official Catalina Crush drink to re-energize! To best describe this hill to those of you that haven't ran it, check out this poem written by Scott Cline, a Catalina Eco Marathon legacy runner.

"For three years now, as I approach the base and look up at those people WAY up there at the top, I say a LITTLE PRAYER. While I'm on it, I think of my farm heritage and low-gear strength requirements TRACTOR PULL as as I start I always have HIGH HOPES that's when I get to the top I can feel the Ancient Roman victory cheer VENI_VIDI_VICI (I came- I saw- I conquered) and head on down to the aid station feast." Scott Cline

Half Marathon Course

This beautiful trail half marathon course starts runners in the city of Avalon and quickly climbs to over 1600 feet in elevation. Runners enjoy the expansive Catalina Island Conservancy Nature Preserve with its spectacular vistas while being challenged by the rugged terrain. They'll also have the special thrill of knowing they're in bison territory—the Conservancy man-ages a free-ranging herd of 150 of the majestic animals.

10k Course

The Eco Marathon 10K will begin in the middle of Avalon and then run through city streets, up and down hills, reach the outskirts of the city before heading to over 2.5 miles of trails just above the city landscape.  You will run around Avalon’s most famous landmark: the Casino building, by the Wrigley’s house, turn around at the Wrigley Memorial and Gardens, and then on horse trails, past the golf course and back into town – finishing by the fountain, the landmark of downtown Avalon.
